How you could start noticing differently by removing one sense.
I was an early customer of Bose and their noise-cancelling headphones when I got to try them out on a transatlantic flight many years ago. “Game changer” as the saying goes, so I have always worn Bose headphones on flights ever since to cut out the noise from the engines.
I recently bought a new pair as my old ones were a bit tatty (at about a decade old!). The new pair, of course, no longer has cables but Bluetooth, plus a button on the side to switch between noise-cancelling and “aware” modes. Having never taken my old pair when on a train and out and about in London, I took the new set with me on a recent trip. It was fascinating to me. I imagine many use them to shut out the world, yet for me, they had a very different impact. When not being assaulted by background noise on the train or walking down the street, I suddenly started to notice more with my vision. I was blown away by the difference when I toggled the “aware” switch on and off.
In the absence of one sense (hearing) I started “noticing differently” by focusing on my vision and what I could see. It was so different.
Writing this also reminds me that I was talking to someone recently about how much I had learned this year from being engaged with supporting Croydon Vision (a remarkable charity supporting the vision-impaired). They told me of an exercise they sometimes do, which is simply to take off their glasses (like me they have poor eyesight when uncorrected) and then walk across a busy part of the city. I then tried it after the meeting and wow, it really is different to not have ease of vision.
One of my favourite phrases I have ever been taught is “awareness is the greatest agent for change”. Try eliminating (or simply greatly reducing) the amount you can rely on one of your senses and be aware of how you “notice differently”.
